<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply system incorporated in a cogeneration system or a solar system, having a stable hot water supply temperature when changing over from a heat storage use state to a heat source machine use state. <P>SOLUTION: This hot water supply system 10 has a temperature stratification type heat storage tank 20, a mixing unit 24, and a heat source machine 22. A hot water supply continuable time capable of keeping on supplying hot water of a set temperature or above from the heat storage tank 20 is calculated by use of a detection water amount of a second water amount sensor 47, a detection temperature of a water supply thermistor 48, a detection temperature of an upper thermistor 35, and the set temperature set by a remote controller 23, and the heat source machine is forcibly ignited when the calculated hot water supply continuable time is one minute or below. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
